For your Presidents' Week (or whatever they call it these days) enjoyment, the birth month of all the presidents, plus presidential candidates:
This is...not evenly distributed in terms of quality.
January: Nixon, FDR. McKinley, Fillmore
February: Reagan, Lincoln, W.H. Harrison, Washington
One of these things is not like the others. Then again, at least Harrison did no damage in office.
March: Cleveland, Tyler, Jackson, Madison
(Mitt Romney was born in March)
April: Grant, Buchanan, Monroe, Jefferson
May: JFK, Truman
(Rick Santorum was born in May)
June: George H.W. Bush
(Newt Gingrich was born in June)
July: George W. Bush, Ford, Coolidge, J.Q. Adams
August: Obama, Clinton, LBJ, Hoover, B. Harrison
Poor Benjamin Harrison, in this company.
There wasn't room for another one.
October: Carter, Ike, TR, Arthur, Hayes, Adams
Character of this list changes a lot if you ignore History's Greatest Monster.
November: Harding, Garfield, Pierce, Taylor, Polk
Pierce is the only one who was alive five years after being elected. Polk rather stands out in this crowd.
December: Wilson, A.Johnson, Van Buren
